Welcome to your interview.
The question is on your right: Validating Data Integrity. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
How do you validate data integrity when importing large datasets from external sources into your BI models for Hologic?
